Improving the design and characteristics of acoustic transducers
Abstract
The design of piezoelectric transducers was studied by comparing commercial ceramics, computing the resonance frequency, and studying electronic devices which use them. Nonpiezoelectric transducers were also studied, including an experimental condenser transducer and a commercial electret transducer. It is shown that piezoelectric transducers are the best adapted to detecting acoustic emission. Capacitive pickups can be used where frequency selectivity is a problem.
